cheapest data plan? ? I have tmobile and just got the new pearl flip. I want to use blackberry messenger but I keep getting mixed information from Tmobile reps. One told me that it was free for me to use because bbm goes through cell signals, but this contradicted everything I researched online. Another one told me that I definitely needed to purchase a data plan - specifically the $19.99 unlimited data plan which includes unlimited web browsing and every type of messaging. There's another data plan for $9.99 that offers unlimited email. Some users on line have said that this plan supports BBM, others say no.

So my question is, do I need a data plan to use blackberry messenger? and if I do, does the cheaper $9.99 unlimited email only plan allow me to use blackberry messenger?

Thanks alot.
